While driving my vehicle on the interstate the car lost the ability to accelerate. All of the dashboard lights came on and I had to coast to the side of the interstate. After restarting the vehicle I was able to drive it but I cannot take the vehicle over 30 mph now without it shuttering and having acceleration issues. This is a serious and life threatening issue that needs to be fixed free of charge. I have found other reports of this happening but I see no recall information. This needs to be fixed before Mazda has lawsuits filed against them. This is a manufacturing error and not a usage error. Please look into this.

I was driving my Mazda 2013 Cx-5 on the highway, when it suddenly lost power and would not accelerate. I pressed the the accelerated all the way to the floor and my vehicle would not accelerate. The engine light, low tire, and traction symbols all were lid up on the dashboard. I drove the vehicle back home at 20 mph as this is the maximum top speed the vehicle would accelerate. I will check to see if there is a recall for this safety issue that can be life threatening.

This has been happening for the last 2 years. I've taken it to 2 different Mazda dealerships for a total of 5 times and they cannot duplicate the issue or find any problems running diagnostics. My car has 50,000 miles on it and is a 2013 Mazda Cx-5. when I bought it had 20,000 miles on it and I started noticing a few months after I bought it. This issue happens mostly when: 'I'm turning left from a complete stop 'turning left while coasting toward a stop sign and then speeding up once it turns green 'merging into traffic going left or right 'turning right from a complete stop or while coasting to the red light and speeding up once it turns green car stalls/hesitates/lingers as if I'm not accelerating. As though the car was in neutral instead of drive. The RPM increases but the car does not move (unless it was already coasting and continues to move from momentum). It feels as though the transmission is not shifting quick enough into the right gear and I notice this while I'm usually at a lower speed trying to accelerate into traffic. I am often scared that a car will hit me from behind (or the side if I'm turning left) as I turn into traffic. It's the equivalent of someone turning into heavy traffic and then stopping. This will cause an accident and I'm hoping it doesn't take a fatal or near fatal accident before Mazda realizes there is a definite problem with this car.

On 2 separate occasions (5/27/2017 and 6/15/2017) while on the freeway while in stop & go traffic, my vehicle suddenly seemed to lose power, and unable to go more than 20 mph. The tire pressure, traction control, emergency light comes on. Both times I have safely been able to make it to the shoulder. The first time, I had my car towed to auto repair shop. Their $300 diagnosis reported nothing wrong with the car. The second time, I turned my car off & on again on the shoulder. The check engine light stayed on and I and was able to drive to my destination. The check engine is now back off, but I have dropped it off at the same auto repair shop, and they are replacing an air flow sensor in hopes that this resolves the problem. This will cost us another $300. Both times I had my 18 month old in my car. I am deeply concerned.

When driving approximately 65mph or sometimes less the tire pressure, traction control, emergency light comes on. The car seems to lose power and shut down. It happens countless time twice with my two-year-old daughter on the highway. When I take it to the mechanic they run diagnostics test and can't pick up any codes. Because its not duplicating any issue they return the car to me after they reset all the computer. But the issue is still not resolved. I would lose power to the car and my brakes are sometimes not responsive. I would coast with my emergency light on until I can stop my car. Sometime my hazards light would frequently flash at a fast speed than stop. I took it to two Mazda dealership to see if they can have resolved the issue but they cannot duplicated what going on. I did some research on my own and found countless complaints about the same issue I'm having and no mechanic can figure out the issue this car is junk. This have started the first week on Dec. 2016 it has been in two shop over the past 4 month. The first shop I took it to had it for a whole month and the second shop had it for two week. At one point when I was told my car was fix I came to pick it up. The car would not start at all it was not even reading my keys. The car does not have 100K miles on it. I don't do a lot of driving. This is hazardous

For the past 5 months my car will appear to have shut down while driving. I was driving on city streets going about 15 - 45 mph. I work from home or go to the office twice a week. I drive my kids to school during the week. I don't do much commuting. All electrical components shut down then reboot within seconds, and the car makes beeping sounds like I just started the car. The car will not stop or slow down, but if I come to a complete stop at a light, the car will be very slow to accelerate but I can get it back up to the speed limit after a very slow start. I have called aaa on one occasion and took it to a shop on another occasion. They both say it is battery related due to the wrong batter being installed but it is the battery size in the system of an orielys auto parts store. Every time I replace the battery and the issue appears to go away for a couple weeks to a month. The last battery replacement I purchased a stronger batter than in their system as per the advisement from the auto shop. It seemed to fix it again but after a month the car did the same thing.

5 seconds after starting the vehicle it suddenly went into unintended acceleration from 5mph to about 40 mph. I immediately applied the brakes but the car would not slow down or stop. I then shifted into neutral which did nothing, then shifted into park, which did nothing. Still applying the brakes I tried numerous times to shut (push botton) ignition off but that was unresponsive. I hit a street sign which slowed me down and the car finally came to a stop but the engine was still reving loudly for another solid minute. I again was pushing the ignition button and the car then suddenly turned off.

- Westport, CT, USA

Traveling residential street approx 40mph. Prepared to slow for upcoming light and traffic applied light pressure to brake vehicle started to slow felt what thought was a downshift except accelerator went to floor and car accelerated brake fighting acceleration vehicle not slowing thought to shift into neutral engine raced wildly, vehicle came to stop motor racing, hit off button and motor finally stopped. Restarted and vehicle back to normal called dealer took for check next day Mazda and independent contractor supposedly inspected found no problem checked their black box no supporting data. Concluded I was using 2 feet to drive I have driven for over 50 years and have never used 2 feet to drive I taught my children and helped teach my grandchildren and never allowed 2 feet to be used in driving. Mazdas solution was to install a new data box to collect more data if it happened again with no concern for my family and their safety or that of others on the roads plus my insurance would be put at risk along with potential lawsuits against me personally as I know Mazda did not even attempt to figure what parts might cause this problem a good company would troubleshoot the problem assess which parts could cause the problem replace the most logical parts and try to solve the problem. Mazda just wants to put the problem back on the road with no troubleshooting attempts or skills. I know one other person who's teenage daughter has had this happen twice and they say they can find no problem one of hers resulted in an accident. My case # [xxx] with Mazda today I traded in this vehicle. Mazda says the vehicle is safe although they declined to send me an email confirming this sorry to say it will probably be sold to some other unsuspecting person. Hope no one gets hurt.

Was driving normally when all of the sudden engine light came on and other lights in the cluster came on and the vehicle did not shift. Could not pass 20 mph. Had to stop the car and turn it off, later turn it on and just the engine light was lit. After getting home and letting the car cool down the problem went away.

Car fails to start X 2 but then starts. Briefly, accelerate car as I merge on the fwy. Car begins decelerating, lurching so I struggle to steer to the side of the fwy. Many warning lights flashing, no brakes, no steering ability. Turn of car. Try but unable to turn on car. Call towed. Mechanics say car starts right up and nothing wrong. Funky other little things like, I open rear hatch to put item in car (keys are in house). Attempt to close hatch but it won't latch. Obtain remote and try to use it to engage latch. No luck. Last month, can't start car. Call aaa, technician starts car but says to replace batteries in remote. Take to dealer. Batteries fine and no findings. 4/17/14 start car and proceed to back up. All warning lights are on. Unable to steer or depress brakes. Turn off car. One hour later, car starts and all is copacetic.

Was passing a semi-truck full throttle on a hilly 2 lane roadway.....engine shut down and multiple dash warning lights came on....was able to coast to a safe stop and turned off ignition and restarted vehicle. Very scary!! took the vehicle to the dealer and they could not find a problem.

- Mesquite , TX, USA

While on a very busy road, all of a sudden the accelerator stopped working and my speed began to drop rapidly. At the same time, the traction control warning light and tire pressure warning light came on. It was as if the car had completely lost power. I was able to coast to the side of the road and turn the car completely off. I got out and checked all of the tires and they were fine. When I turned the car back on, the warning lights did not come back on and the car ran normally.

- Palmyra, PA, USA

I had just exited the freeway after driving 25 miles and was stopped at a stop light. When the light turned green and I stepped on the accelerator, the vehicle engine revved high and did not shift gears in the automatic transmission. I could not get the vehicle out of first gear or over 20 mph. I was able to get the vehicle to a safe location and once it had cooled overnight the transmission shifted normally. I did not drive it more than a block for fear it would happen again and the vehicle is currently at the dealership for repair.

While changing lanes on highway from a stop, it felt as though the car was in neutral instead of drive. The RPM increased but the car did not move. I have also noticed upon sudden acceleration from around 30 that I get a similar response. Mazda states vehicle performing as by design. Car does not seem to down shift quick enough on acceleration.

- Jonesboro, GA, USA

While the brake is held down with the left foot and a slight pressure is put on the gas pedal the car will suddenly surge forward. It can move about two feet before I get the brake on hard enough to stop the car. It feels as if the vehicle was struck hard from behind. The dealer has looked at it twice and suggested that the bog for "break over gas" logic system is being fooled by the combined pressure on the brake and gas at the same time, I.e., if, while both pedals are pressed, if the brake pressure is slightly released while the gas pedal is still slightly depressed the computer thinks the it has to "catch-up with the gas pedal and it surges forward. It has happened five times. It has never happened without both the brake and gas being simultaneously applied. It becomes a safety issue when it happens at a busy stop signed intersection while waiting to make a left turn across oncoming traffic, I.e., a pedestrian could be struck. I try to avoid this using this technique but it is a habit that I'm sure many drivers have.

While driving on the left lane of a busy los angeles highway at approximately 55mph, all of a sudden the accelerator stopped responding and my speed dropped rapidly. At the same time, the traction control and tire pressure lights turned on. Immediately, I turned on my hazard lights and pulled into the right lane. Unfortunately, I was in a tunnel with no shoulder. When the vehicle's forward momentum ran out, I came to a complete stop after cruising for approximately 100 feet. After my vehicle stopped, I was able to accelerate again and pulled off the highway. I turned the engine off, checked all tires (all looked normal), and restarted the engine. The warning lights were all off at this point, and the vehicle responded normally. This was a disturbing and dangerous situation. I will describe it at my 10,000-mile service, but it does not seem like others who have had this problem have been able to solicit an adequate response from Mazda.

- Pasadena, CA, USA

Pulling in to parking space with foot on brake. Vehicle would not stop and couldn't turn the steering wheel. Car suddenly accelerated and jump curb and ran into side of building. Brake pedal was hard to press and even tried pumping brake, but vehicle would not stop. Engine speed did not change when pumping brake. Vehicle was only three weeks old and had a major malfuntion with braking and steering.

- Townsend, MA, USA

The proximity of the pedals seem to be too close. Some footwear may snag when attempting to brake have noticed twice since purchasing car on 9/22.
